[Patch net-next 4/9] net: dsa: microchip: move struct mib_names to ksz_chip_data

Arun Ramadoss
2022-05-17T09:47:01Z

The ksz88xx family has one set of mib_names. The ksz87xx, ksz9477,
LAN937x based switches has one set of mib_names. In order to remove
redundant declaration, moved the struct mib_names to ksz_chip_data
structure.
